Economic Analyses
EPA conducts climate economic analyses to estimate the economic and environmental effects of potential domestic climate change mitigation programs and strategies. Given the complexity of economic and environmental interactions underlying the climate change issue, no one model can address all of the questions surrounding a climate change economic analysis. To provide an accurate representation of potential climate change mitigation programs and strategies, EPA employs an array of modeling tools and data. For more information about the modeling tools used by EPA, please visit the Climate Economic Modeling page.
